SPECIFICATION forming part of uLetters Patent No. 601,752, dated April 5, 1898. Application lecl February 15, 1897. Serial NO- 623,537. (No'model.)

To all whom/ it mag/,Concerm Be it known that LHARRYC. HoRNIsIL a citizen of the United States, residing at In-j f dianapolis, in the county ofMarion and State of Indiana, have invented certain new and useful Improvements in Vapor-Burners; and I do hereby declare the'following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appe'rtains to make and use the same. f

My invention relates to improvementsin vapor-burners; and the objects in view are to simplify and cheapen the construction of the burner as a Whole, to adapt jit to be readily dismembered for cleaning or fora renewal of any of its impaired parts, and to provide a newand improved combined vapor cut-off and guide, by the use of which cut-off a subflame may be maintained.

Other objects andadvantages of the inven-` tion will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure "1 is a side elevation of my improved vapor-burner. Fig. 2 is a top plan view of the same with the burner-cap removed. Fig. 3 is a bottom planA view of the retort. Fig. 4 is a transverse sectional view of the retort in detail, the construction of retort being slightly modified, as

. will hereinafter appear.

Like numerals of reference indicate similar partsin all the figuresof theY drawings.

The retort consists of the annular hollow chamber 1, which incloses a solid bottom 2, at the center of which is formed an opening 3. `This bottom 2 may be cast integral, and

` preferably is so cast, with the hollow. annular chamber'l and may be located at the kbottom edgeof said chamber, as in Figs. 1, 2, and 3, or located at any suitableV point between the bottom and top edges thereof, as indicated at 4, Fig. 4. L

The bottomplate 2 may have its opening provided with an annular mixing-tube 5, cast thereon, the same rising to a `point about on a level with the upper side of the chamber 1 of the retort, or, as preferred, such tube 5 may be cast on a separate and removable disk or plate 6, adapted toV rest upon the bottom plate 12, in which instance, as best shown in Fig'.'4,

they lower end of said tube projects below the said disk, taking within and fitting the opening 3, with which it (the bottom) is provided. It is therefore perfectly obvious that the disk andthe mixing-tube may at any time be removedfor 'cleaning or for the substitution of a smallerY mixing-tube or'a new one to take the place of one burned out.- By extending the lower end of mixing-tube through the central opening in the bottom plate soot cannot accumulate betweenthe two plates and dis. turb the snug fitting of these parts.

An annular rib 7 surrounds the upper outer edge of the annular chamber l of the retort, serving to strengthen the same at this point,

and having its in ner surface inclined or Iiared,

as shown, will serve to properly direct the I the annular chamber 1 I also provide the same with openings 10, closing ,the same securely with threaded plugs 11, which may be readily removed by the application of a wrench.

A hollow leg 12 depends from the under side of the annular chamber 1 and is provided at its lower end with a threaded opening 13 for the reception of a closing-plug 14, which,passing through a suitable hole formed in' the tray 15, serves to not `only close the lower end of the said leg, but also to clamp and holdin position the vaforesaid tray l5 undervand'in proper relation to the retort.v

Above the tray` the leg is' provided-with diametrically opposite openings 16 and 17, the former being occupied by the supply-pipe 18 and the latter by a removable threaded plug 19, whereby access'to the said'leg for cleaning purposes is given.

A lianged opening 20 is located in the bottom of the annular chamber 1 diametrically opposite to the point of location of the leg 12,'

and in the same is threaded a bushing 21,

which receives the upper end of the usual needle-valved "vapor-discharge' 22, the Vsame being'of ordinary construction and therefore not requiring any particular mention.

Pivoted eccentrically to the bottom plate IOO 2 of the retort, as indicated at 23, is a substantially triangular plate 24, the same forming a cut-off. Cast or otherwise secured to the under side of the said cut-oft plate is a pair of segmentally-shaped open and closed tubes 25 and 26, respectively, the same being located at an acute angle to each other and connected by an intermediate web 27.

The cut-oit plate 24C is provided with an opening 29, (see dotted lines, Fig. 3,) which when the plate is moved so that the tube 25 is in line with the mixing-tube forms a continuation of the said mixing-tube and the tube 25. That part of the plate 24 which is above or in line with the tube 26 is imperforate or solid, so that when the latter tube 26 is in line with the mixing-tube communication between the two tubes is interrupted or cut off. The tube 26, however, immediately below the cut-off plate is provided with a horizontal escape-slot 30, through which oil and vapor may escape into the pan or tray for the purpose of a preliminary starting and to maintain a subfiame underneath the retort after the operation has commenced and when it may be desired to maintain vaporization within the retort until such time as it maybe desired to use the burner at its full capacity. A curved keeper-bar 3l is located under the retortand loosely connes the arm 28,which projects from the cut-off plate 24 between the two tubes 25 and 26. This bar has at its ends upwardly-projeotin g posts 32, which at their upper ends abut against lthe bottom of the retort and are bored for the passage of screws 33, which are passed therethrough and into l the bottom of the retort for the purpose of site direction the opposite tube 26 will be in line with the vapor tube or opening, and the cut-off plate will be interposed between the two. By thus forming the cut-o it will be seen that the gas and air will be mixed therein and a subiiame be ejected or discharged from the slot at the upper end thereof below the cut-oftl plate. This sublame, it will be understood,will be sufficient to maintain the state of vaporization of the oil in the retort, so that the burner can be instantly started by swinging the cut-oft plate to the opposite side, so as to bring the vapor-tube in line with the mixing-tube and vapor-discharge.

The interior of the burner-cap 9 may be fiat, or, as shown by dotted lines, Fig. 1, it may be concaved, and in either instance is surrounded by a vertical flange 34, which projects at its upper end above the exterior or dome oi the cap to form a surrounding or, rather, flange.

strengthening-Han ge or thickened portion 35.

This wall or flange 3i is preferably provided' at intervals with perforations 36, the same being arranged in annular alinement and in a lower plane and also in annular alinement and preferably alternating with the perforations 36. Said flange is further provided with openings 37 of substantially keyhole shape, inasmuch as they consist of upper circular openings communicating by means of narrow slits withthe bottom edge of the cap These openings, it will be understood, constitute the means of escape of the dame, and after they thus escape they are directed upwardly by the flared flange 7.

The operation of this burner does not materially differ from that of others, and may be briefly said to consist in permitting a suitable quantity of oil to pass through the feedpipe 18 into the retort-chamber l, after which the supply is cut ofi'. A small quantity of oil being permitted to escape into the tray is now ignited and warming the retort vaporizes the oil in the retort, the needle-valve being oper-` ated to permit the escape of the vapor into the tube 25, from which it passes into the tube 5, at the upper end of which it is ignited. During its passage through `these tubes it of course mixes with the air, as is usual in this class of inventions. When it is desired to shut o the burner temporarily and to maintain such a subfiame as will maintain a vaporization, the cut-off plate is moved so as to bring the tube 26 between the vaporopening in the needle-valve and the mixingchamber, whereby the vapor escapes through the slot 30 in the tube 26 and heats the retort to such an extent as to bring about the dcsired result.

I do not limit my invention to the precise details of construction herein shown and described, but hold that I may vary the same within the knowledge of the skilled mechanic without departing from the spirit of my invention or sacriticing any of its advantages.

11": desired, the mixing-tube 5 may be tapered or decreased in diameter toward its upper end, such being indicated in Fig. 4c by means of dotted lines. It will also be understood that any desired shape of opening may be formed in the burner-cap.
